   Whether a particular service constitues a skilled nursing service is ordinarily determined
      on a case-to-case basis. As a general rule, however, the counselling and evaluation
      services required by an elderly patient suffering from a diagnosed psychiatric disorder
      that required active treatment in a psychiatric institution requires the skills of
      a  psychiatrically trained
         nurse. (A psychiatrically trained nurse is a nurse who has  special  training and/or experience beyond the standard curriculum required for the R.N.)
      The special training of such nurses enables them to interpret the underlying meaning
      in the patient"s actions and to evaluate the need for the psychiatrist to change the
      plan of treatment or to reschedule visits to the psychiatrist"s office. Conversely,
      if the visiting nurse has not been trained in psychiatric care, that nurse's visits
      would not be reimbursable since they are not deemed “reasonable” to the treatment of the patient"s illness, unless the entire plan of treatment consists
      solely of injections of fluphenazine, a behavior modifier, which can be furnished
      by a nurse, that has not been “psychiatrically” trained. It is expected that an individual whose psychiatric disorder is severe enough
      to require the special skills of a psychiatric nurse will be under the care of a psychiatrist
      and that the plan of treatment calling for the services of a psychiatric nurse will
      be established and reviewed by the psychiatrist.
   
   
   In effect the law precludes an HHA which is  primarily for the care and treatment of mental diseases from participating in the program.
      However, this exclusion does not preclude payment where psychiatric nursing is furnished
      by an agency which is  not primarily for the care and treatment of mental diseases. Should the intermediary find that
      the number of bills submitted for individuals with mental disorders is significant
      enough to raise the possibility that an HHA is primarily for the care and treatment
      of mental diseases, it notifies the CMS RO.
